Though the universe contains all kinds of wonderful things that most people are not aware of.

I think that it is possible for us to build a saucer shaped craft, and I think that if there are beings that are more advanced technology wise, then they should be able to build better systems.

Go to this site and scroll down about half way , is that thing real and is it flying?

Model saucer that works on the Coanda effect?

Why could it not be real and if this thing works, then why could it not be possible to improve the operation of such a device?

For those with mathematical aptitude there are lots of numbers to study.
